X 3 Claims. 1-

This invention relates'to containers such as pouches, bags and the likehaving oppositely disposed wallsproviding a linear mouth opening, andthe invention has particular reference to a sliding closure thereforwhich resiliently maintains the oppositely disposed walls in closedrelation and which providesvconvenient means for releasing the walls topermit of the spreading of the same apart for gaining access to thecontainer.

An object of the invention is to provide a container of said characterwith a sliding closure which is adapted to resiliently maintain theopposite Walls in closed abutting engagement throughout the lengththereof for effectively closing the container.

Another object of the invention is to provide a sliding closure havingopposite portions which are slidably arranged in longitudinallyextending tunnels in the oppositely disposed walls of the containerdefining the mouth opening and which portions hold the walls of thecontainer in closed relation by the inherent spring tension thereof.

Still another object of the invention is to provide a closure of theindicated character which is slidable in the tunnels of the oppositewalls of the container throughout the entire length thereof to afford awide-opening mouth therefor.

With the foregoing and other objects in view, reference is now made tothe following specification and accompanying drawings in which thepreferred embodiment of the invention is illus trated.

In the drawings:

Fig. 1 is a view in elevation of a container provided with a slidingclosure constructed in accordance with the invention.

Fig. 2 is a longitudinal sectional view taken approximately on line 2-2of Fig. 1.

Fig. 3 is an enlarged fragmentary sectional view taken approximately online 3-3 of Fig. 2.

Fig. 4 is an enlarged fragmentary sectional view taken approximately online 44 of Fig. 3.

Fig. 5 is a vertical sectional view taken approximately on line 5-5 ofFig. 1.

Fig. 6 is a fragmentary cross-sectional view taken approximately on line6--6 of Fig. 1.

Referring to the drawings by characters of reference, the invention isillustrated in its application to a pouch l0 having oppositely disposedlongitudinally extending side walls and 12 which are integrallyconnected together alon the bottom edge I3 and with the side wallsconnected together at their ends by stitching l4 and I5. The side wallsH and [2 are fashioned 2 of flexible material and as illustrated thesame may have a waterproof inner facing 16.

The upper longitudinal edges of the side walls form a linear mouthopening I1 and in order to provide means for securing the said walls inclosed relation, the same are folded inwardly along their free upperedges with the inwardly folded portions secured to the body of the wallsby lines of stitching l8 and [9 to thereby form longitudinally extendingtunnels and 2| at the upper ends of the walls, which tunnels are closedat one side of the pouch by the line of stitching l4 and are open at theopposite ends thereof. A spring closure member 22 consisting of a lengthof spring material bent upon itself provides oppositely disposed legs 23and 24 which are slidably arranged in the tunnels 20 and 2| and are of alength to extend from end to end of the tunnels and to protrude throughthe open ends thereof with the protruding ends connected together by arebent portion 25.

The rebent portion 25 is of looped formation in order to normallytension the legs into abutting engagement throughout the length thereofwhereby the same retain the upper edge portions of the side walls H andI2 in close fitting engagement throughout the length of the tunnels. Theleg members 23 and 24 are slidable in the tunnels throughout the lengththereof and have their inner ends formed into downwardly directed loops26 and 21. The rebent portion 25 is located adjacent the open ends ofthe tunnels when the legs 23 and 24 are engaged therein throughout thelength thereof and in order to limit the outward movement of the legsand prevent disengagement of the same from the tunnels, the tunnels arerestricted by a line of stitching 28 which extends through the oppositeside walls II and I2 and through the inturned portions thereof providingthe tunnels. The downwardly directed loops 26 and 21 are adapted toengage against the inwardly curved portions 29 and 30 of the walls H andI2 adjacent the line of stitching 28 for retaining the legs in thetunnels, it will be understood that the cross-sectional area of thetunnels above the inwardly curved portions 29 and 30 of the walls H andI2 is sumcient to slidably receive the legs 23 and 24.

What is claimed is:

1. In a container, oppositely disposed side walls connected togetheralong three edges thereof and unsecured along the upper edges to providea mouth opening, said walls having inturned upper edge portions securedto the body thereof in spaced relation from the upper edges of saidwalls to provide tunnels extending longitudinally of said walls andopening through one side of the container, a closure consisting of alength of spring material bent to provide a spring loop and oppositelydisposed confronting legs, said legs being of a length to engage in saidtunnels from end to end thereof for resiliently maintaining the upperedge portions of said side Walls in closed abutting relation, and saidlegs being slidable into protruding relation from saidtunnels to permitof the spreading of said side walls apart for opening the container.

2. In a container, oppositely disposed side walls connected togetheralong three edges thereof and unsecured along the upper edges to providea" mouth opening, said. walls having inturned upper edge portionssecured to the body thereof in spaced relation from the upper edges ofsaid walls to provide tunnels extending longitudinally of said walls andopeningj-through one side of the container, a closure consisting of- :alength of spring material bent to provide a spring loop and oppositelydisposed confronting legs, said legs being of a length to engage in saidtunnels from end to end thereof for resiliently maintaining the upperedge portions of said side walls in closed abutting relation, and saidlegs being slidable into protruding relation from said tunnels to permitof the spreading of said side walls apart for opening the container andhaving, inner end portions rebent into overlying relation with said legsadapted to engage against the walls of the container adjacent the openends of said tunnels for retaining the inner ends of the legs in thetunnels.

,.nels fromendto end thereof for resiliently maintaining the upper edgeportions of said walls in closed abutting relation, and said legs beingslidable into protruding relation from said tunnels to ,,=perm i-t of.the spreading of said side walls ap'artior opening the container andsaid legs havingtheir inner end portions bent into angular relation andadapted to @engage against the walls of theucontainer adjacent the openends of the tun-nels for retaining the closure in protruding relationfrom the tunnels.
